HikariPool PoolInitializationException添加了一些@Test方法

我正在與HikariCP2.6.1。HikariPool PoolInitializationException添加了一些@Test方法

我正在與MySQL和JUnit 4.x和平。就在今天，我添加了一個新的@Test方法，現在測試失敗。如果我把@Ignore這個新的@Test所有的工作當然。如果我把@Ignore到其他以前的@Test那通過，併到這個新的@Test我刪除@Ignore所有的工作。

因此加入新的@Test方法，工程或需要DB連接出現以下異常：

Caused by: org.springframework.beans.BeanInstantiationException: 
Failed to instantiate [javax.sql.DataSource]: 
Factory method 'dataSource' threw exception; 
nested exception is com.zaxxer.hikari.pool.HikariPool$PoolInitializationException:

... 
Caused by: java.lang.ArrayIndexOutOfBoundsException: 24 
    at com.mysql.cj.mysqla.io.Buffer.readInteger(Buffer.java:271)

我目前的設置是：

@Bean(destroyMethod = "close") 
public DataSource dataSource() throws SQLException { 

    HikariConfig hc = new HikariConfig(); 

    hc.setDriverClassName(environment.getProperty("mysql.driverClass")); 
    hc.setJdbcUrl(environment.getProperty("mysql.jdbcUrl")); 
    hc.setUsername(environment.getProperty("mysql.user")); 
    hc.setPassword(environment.getProperty("mysql.password")); 

    hc.setPoolName(environment.getProperty("hikaricp.poolName")); 

    hc.addDataSourceProperty("databaseName", environment.getProperty("hikaricp.databaseName")); 
    hc.addDataSourceProperty("cachePrepStmts", environment.getProperty("hikaricp.cachePrepStmts")); 
    hc.addDataSourceProperty("prepStmtCacheSize", environment.getProperty("hikaricp.prepStmtCacheSize")); 
    hc.addDataSourceProperty("prepStmtCacheSqlLimit", environment.getProperty("hikaricp.prepStmtCacheSqlLimit")); 
    hc.addDataSourceProperty("useServerPrepStmts", environment.getProperty("hikaricp.useServerPrepStmts")); 

    HikariDataSource hds = new HikariDataSource(hc); 

    return hds; 
}

而且

hikaricp.poolName = "hikaricp-channels-pool" 
hikaricp.databaseName = batch 
hikaricp.cachePrepStmts = true 
hikaricp.prepStmtCacheSize = 250 
hikaricp.prepStmtCacheSqlLimit = 2048 
hikaricp.useServerPrepStmts = true 

mysql.user = root 
mysql.password = somepassword 
mysql.driverClass = com.mysql.cj.jdbc.Driver 
mysql.jdbcUrl = jdbc:mysql://localhost:3306/batch?autoReconnect=true&useSSL=false

需要額外的配置嗎？

阿爾法

版01：

  • 來源：mysql.jdbcUrl = jdbc:mysql://localhost:3306/batch?autoReconnect=true&useSSL=false
  • 要：mysql.jdbcUrl = jdbc:mysql://localhost:3306/batch?useSSL=false

版02：

  • 補充：hc.addDataSourceProperty("maximumPoolSize", 2);

關於DEBUG報告：

從上面我沒有意識到我的hc.addDataSourceProperty("maximumPoolSize", 2)體現在

dataSourceProperties............{ 
    password=<masked>, 
    prepStmtCacheSqlLimit=2048, 
    databaseName=batch, 
    cachePrepStmts=true, 
    useServerPrepStmts=true, 
    maximumPoolSize=2, <------ 
    prepStmtCacheSize=250}

和maximumPoolSize.................10

測井輸出遵循與此錯誤堆棧跟蹤

顯示於其它地方的其它相同的錯誤消息與：

Pool stats (total=1, active=0, idle=1, waiting=0)

多頭上面所示的兩個輸出都位於中部.log文件。就在底部，出現以下很多次。

現在只是改變：

//hc.addDataSourceProperty("maximumPoolSize", 2); 
    hc.setMaximumPoolSize(2);

所有現在通過。

從這個經驗，我會通過GitHub出現一些'問題'如何改進當前文檔的建議。

我想你絕對不想autoReconnect。此外，對於測試，您可能不需要池大小爲10，請嘗試1或2.還要爲com.zaxxer.hikari啓用DEBUG日誌記錄，並確保池在測試之間正確關閉。

添加了'Alpha'部分，只是好奇和困惑，爲什麼使用'2'而不能使用'10'。 –
